Naval brass is a type of brass alloy, known for its excellent strength and corrosion resistance in marine environments. It is primarily composed of copper, around 60-70%, with zinc making up another 30-40% of the alloy. Additionally, small amounts of tin and lead may be added for further enhancement of specific properties. The proportions of these elements may vary slightly depending on the specific grade of naval brass.
Naval brass alloys are widely used in the naval industry due to their remarkable resistance to seawater corrosion, biofouling, and stress cracking. Their ability to withstand the harsh conditions of saltwater and damp atmospheres makes them ideal for various marine applications. Naval brass alloys are commonly employed in the production of propellers, ship fittings, valves, decorative components, and other parts that come into contact with seawater.
The high copper content in naval brass provides excellent resistance to corrosion, while the addition of zinc contributes to its commendable strength and formability. Tin and lead can help improve machinability and hardness. Naval brass is often characterized by its attractive golden or yellowish color.
Overall, naval brass is a durable and versatile brass alloy that offers exceptional resistance to corrosion and tarnish in maritime environments. Its combination of strength, workability, and resistance to corrosion make it a valuable material in marine applications and contribute to its widespread use in the naval industry.
The term "naval brass" is a combination of two words: "naval" and "brass".
"Naval" comes from the Latin word "navalis", which means "of or belonging to ships or the navy". It is derived from "navis", meaning "ship". The term specifically refers to anything related to ships, seafaring, or the navy.
"Brass" is a metal alloy primarily composed of copper and zinc. The word "brass" itself has origins in the Old English word "bræs" or "bras", which referred to the metal. The term has Indo-European roots and can be traced back to the Sanskrit word "varcas", meaning "gold".
Therefore, when combined, "naval brass" refers to a particular type of brass that is especially suitable for marine applications due to its resistance to corrosion, high strength, and excellent weldability.
